ANDREW LA'HTI, oF RED LODGE, MONTANA Application il'ed July 25, 1913.Serial No. 781,191.

To all whom 'it may concern.'

Be it 4known that I, ANDREW LAH'rI, a citizen of Russia, residing at RedLodge, in the county of Carbon and State of Monta-na, have inventedcertain new and useful Improvements in Beet-Harvesters, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to a beet harvester and the principal object ofthe invention is to provide a harvester with an improved constructionwhereby the beets may be dug up from the ground and conveyed to a suit`able receiver.

A further object of the invention is to provide an improved diggingmechanism which may be adjusted to dig at the depth desired.

With these and other objects in view, this invention consists of certainnovel constructions, combinations and arrangements of parts, as will behereinafter fully described and claimed.

This invention is illustrated in the accompanying drawings, wherein:-

Figure 1 is a side elevation of the beet harvester. F ig. 2 is asectional view through the harvester along the line 2 2 of Fig. 1. Fig.3 is a perspective view of the digging means. Y

Referring to the accompanying drawings, it will be seen that thisinvention comprises a frame havingthe side-bars 15 and 16 which havetheir forward end-portions 17 brought together and extended to form arms18, which are connected by a block 19. This block carries a pin 20extending through the axle 21 and thus pivotally mounting the axle sothat the axle may be turned when it is desired to turn the machine. Thisforward axle 21 carries the supportin wheels 22 and also carries theeyes 23 with which the connecting-rod 24, for the tongue 2:3, areconnected. The* rear portions of the side-bars 15 and 16 carry bearings28 in which the axle 29 is rotatably mounted. This axle l29 carries thesupporting wheels 30 and constitutes a vdriving shaft for the mechanismto be hereinafter described, since it rotates with the wheels 30 and bymeans of suitable gearings opcrates the mechanism of the digger.

The beet-digger mechanism is carried by the axle 29 and comprises thetwo beams 31 which have their inner end-portions 32 Specication o1'Letters Patent.

curved upwardly and terminating in bear- A fork 38 is connected with theforward ends of the beams 31 and has its outer end formed into a head 39provided with perforations 40 so that a draft appliance may be connectedwith the fork, while the portion of the fork adjacent the bars will rideupon the ground for preventing the blades 35 from digging too deep.

A platform 67 is carried by thesframe and forms a support for one end ofthe angle member 69 which carries the rack 70 of the latch lever 72.

The latch lever 72 is connected with the free end portion of the diggingmechanism by means of the rod 74.

From inspection of Fig. 1 it will be readily seen that by adjusting theposition of the lever the vertical position of the'digging mechanism maybe changed.

From the foregoing description it will be seen that a simple andeilicient digging mechanism has been produced which mav be easilyadjusted and which is so formed as to easily dig the beets and rideevenly upon the ground without danger of digging too deep.

What is claimed is:

1. In a beet digger, the combination with a supporting frame, a beetdigging mechanism pivotally secured to said frame, said beet diggingmechanism'comprising a pair of parallel arms, said arms provided attheir inner ends with upwardly curved portions having enlarged bearingsleev, said sleeves f adapted to abut against each other for holding therear ends of said arms in spaced relation, depending fingers integrallyformed upon the forward ends of said arms, forwardly extending diggingblades integrally formed upon said depending fingers, a block fixedbetween the forward ends of said arms for holding said fingers anddigging blades in spaced relation whereby said digging blades canstraddle the side portions of a. beet for digging the same fromtheground, means carried by said supporting frame and connected to saidarms for vertically adjusting the digging mechanism, a fork fixedlysecured to said arms, whereb said fork will straddle the forward ends osaid arms and brace the same against spreading, said fork provided witha portion extending beyond said fingers'to engage the upper surface ofthe ground thereby preventing said digging blades from digging too deep,said fork terminating in an upwardly extending portion adapted to beattached to a draft appliance.

2. In a beet digger, the combination with a supporting frame, a beetdigging mechanism pivotally secured to said frame, said beet diggingmechanism comprising a pair of parallel arms, said arms provided attheir inner ends with upwardly curved portions having enlarged bearingsleeves, said sleeves adapted to abut against each other for holding therear ends of said arms in spaced relatiomdepending fingers integrallyformed upon the forward ends of said arms, forwardly extending diggingblades integrally formed upon said depending fingers, a block fixedbetween the forward ends of said arms for holding said fingers anddigging blades in spaced `relation whereby said digging blades canstraddle the side portions of a beet for digging the same from thegrourd, a fork fixedly secured t0 said arms, whereby said fork willstraddle the forward ends of .said arms and brace the same againstspreading, said fork provided with a portion extending beyond saidfingers to engage the upper surface of the ground, thereby preventingsaid digging blades from digging too deep,'said fork terminating in anupwardly extending portion adapted to be attached to a draft appliance.

3. ,In a beet harvester, the combination with a supporting frame, a beetdigging member'pivotally secured to said frame, said digging memberprovided with integral offset digtging blades, and a fork ixedly securedo said digging member, said fork provided with a forwardl extendingportion positioned above sai digging blades and terminating in anupwardly extendingv portion of said fork adapted to`ride upon thesurface of the ground above said digging blades for preventing saidblades from digging too deep.

4. In a beet harvester the combination with a beet digging mechanism,said beet diggin mechanism comprising a pair of parall arms, means forholding said arms in parallel spaced relation, means fitting over theouter sides of said arms for holding the same against spreading, saidarms provided with parallel spaced 'digger blades, whereby beets maypass between said blades and be removed from the ground, and means fixedto the forward ends of said arms for limiting the downward movement ofthe same. p 1
